Netflix is reaping the rewards of strong earnings on Wall Street, as investors await the financial results of another high-profile tech giant. Let's look at the tech stocks to watch Tuesday.

Apple earnings after the bell. The company's stock price could absorb another thrashing after it reports second-quarter earnings at the close of the markets on Tuesday.

Investor fears over the lack of another groundbreaking tech product has sent shares tumbling since reaching a peak of $702 on September 19, 2012. Last Thursday, Apple stock hit a 52-week low of $392 before rebounding slightly. Shares are up $3 to $401.90 in pre-market trading.

The question on many investors' minds is how many iPhones did the Cupertino, Calif., company sell during the last quarter. The signature smartphone has faced increased competition from rivals such as Samsung, which launches its highly-touted Galaxy S4 later this week. There's also the Android-based HTC One as well as the BlackBerry Z10, available in the U.S. since last month.

Netflix zooms past $200. Shares of the streaming media giant have rocketed 24% to $216.07 in pre-market trading after revealing it has drawn 2 million new streaming subscribers in the U.S. thanks to its original content.

The company now boasts 29.2 million subscribers in the U.S., Netflix said during its first-quarter earnings call. Netflix raked in $3 million in profit off $1.02 billion in revenue.

As Variety reports, Netflix has surpassed HBO in U.S. subscribers for the first time ever.

This year has been huge for owners of Netflix shares. On January 23, the stock closed at $103.26. It has since doubled in value.
